Loading Images

function SDL_LoadBMP(filename: PChar): PSDL_Surface;

This function creates a surface of the appropriate dimensions and loads a .bmp file into it. The function returns the new surface, or nil if there was an error (not null as stated in the documentation). The function is straightforward to use:

var
  BMPFile : PChar = 'MyBMP.bmp';
  Image : PSDL_Surface;
begin
   SDL_Init(SDL_Init_VIDEO);
   Image := SDL_LoadBMP(BMPFile);        

You can load other types of image such as .jpg and .png with the IMG_LOAD function if you use the additional dynamic link library SDL_image.dll and its header file. See Chapter 3a of Freepascal meets SDL.
